The number of arguments is variable and may be zero. The maximum number of arguments is limited by the maximum dimension of a Java array as defined by the Java Virtual Machine Specification . The behaviour on a null argument depends on the conversion . Returns: A formatted string Throws...
The token {1} is replaced by the second argument after the string template, in other words, the value of the variable second. Note You may think it's odd to start with the number 0. Actually this is very common in software development. Whenever there's a sequence of items that can be...
